Fatented Nov. 19, 192 9 d ROBERT G. ANDERSON, OF ELMHURsT, mw oiai,elamine INTERNATIONAL MOTOR COMPANY, OF NEW YORK, N. Y.,;A- CORPORATIONOF D ELAW ARE BODY-BOLSTER oons'rnnorioiv 1 A plication filed August 13,1927, serial N-ofl 2 The present invention relates to railway carconstruction and deals particularly with cars which are designed tocarry a power,

generating unit as well as the driving units,

5 which, in this particular instance, are the driving motors carriedupon the trucks.

More particularly, the invention relates to a construction which isdesigned to serve as a rigid base upon which the power units are thecar, is such as to provide a unitary base having bearing points whichare capable of carrying the weight of the power generating units inaddition to serving as the usual bracing structure for the car body.

An object of the invention therefore, is to provide a body bolsterconstruction which reduces the weight ofthe car to a minimum and yetserves to impart great strength and rigidity to the body to the car.

A further object of he invention is to provide a mounting for the powergenerating units to be carried upon a rail car, the mounting being ineffect, a unitary and rlgid base, having bearing points over the bodybolster which are designed to carry. the

weight of the units. I

Further and other objects of the invention will appear asthe descriptionproceeds and reference Will now be had to the accom- Figure 2 isa'section taken on line 22 40 of Figure 1 and looking in the directionof the arrows. v

Referring to the accompanylng drawlngs,

a designates a unitary flooror base plate which serves as the base uponwh ch the power'units are to be mounted. Thls floor center sill 6extends, it being composed of side mounted.

manner. 1 The body"jbolsters"arejrepresented i by the reference,charactere. These bolsters are fabricatedfrom plates of metal 0extendiiig from either side of the'oenter sill to the side of the carand beingrivetedto" the -unitary' floor plate a, as wellasthechannelmembers b 'The body bolsters ,0 are spacedwith respectfto theflo0'r plate sd-that thepow'e'r; units to be mounted thereon can beplaced? upon the body bolsters; This is illustrated 1 in Figure 1wherein (Z are 'channels forming the bedplate of'the power una ganad'tmg j .thebe'aring blocks; supporting theoweight-of the units andresting over the body bolsters a.

' Across the under-sides of the body bolsters, I and center sill arefastening' plates kel Theseplates extendfrom sideto side, of the car andare riveted to the plates ,0: and. center sill channelsb.- Between thecent r Sill channels b, a plate. a? is,s,ecured,;,thus completing thebolster 'strengthfor'that section of the car. At the sides of the'car,and over the ends of the floor plate a 'and bolster sections a, are sideplates f., These plates are formed as angles, and riveted to therespective elements. Figure 2 shows the units mounted on the channels a?which carrythe'weights thereof and rest upon the floor plate a over thebody bolsters 0, the pedestals d serving to receive the weight oftherespective units, and atthe same time securing them in position.

It will be apparent, from the above descrip tion, that the unitary basesection provided by the above 'construction'will be of a highly rigidcharacter as-well as being extremely strong. The weight of the resultingstructure is reduced to a minimum without sacrificing any of thestrength and rigidity required for a completely satisfactory base forthe power units carried on the car. The

specific design and construction of the body.

bolsters and co-operating structure may be varied and the invention isnot to be. limited save as defined in the appended claims.

7 While the present invention is especially concerned W1t the portion ofthe underframe over the trucks which transmits the load I thereto,'it isby no ,means limited to such construction, but may be made useofany.
